Robert Kubica has undergone more surgery on his elbow as he continues his rehabilitation following his horrific rallying accident last year.

The surgery, which included the successful insertion of two prostheses in his elbow, is aimed at improving the mobility of his right arm to enable him to better handle a steering wheel.

The latest surgery was undertaken after Kubica spent some time in a racing simulator, and Dr Ruggero Testoni, who performed the operation, is confident it will aid Kubica's return to the cockpit.

"This way the driver can handle the full wheel, whereas previously he was unable to rotate the palm down and was forced to pull the hand off the wheel to in left-hand corners," Testoni was quoted by Tuttosport. "The surgery was preceded by a series of simulator tests," he added.
